At the sleep research meeting in San Antonio this year, there were signs of an impending pharmaceutical arms race in the realm of narcolepsy.
The big fish in a small pond, Jazz Pharmaceuticals, was preparing to market its recently FDA-approved medication: Sunosi/solriamfetol. Startup Harmony Biosciences was close behind with pitolisant, already approved in Europe. On the horizon are experimental drugs designed to more precisely target the neuropeptide deficiency in people with classic narcolepsy type 1 Read more
The results were intriguing, despite the small number of study participants: five, two of whom were pregnant. Detailed information has not been available about immune responses against Zika in humans, especially T cell responses.
Highlights from Mulligan’s abstract:
*All five seemed to have a hole in their immune systems – functional antiviral “killer” CD8 T cells were rare, despite activation of CD8 T cells in general and strong responses from other cell types.
*Cross-reactive immune responses, based on previous exposure to dengue and/or yellow fever vaccine, may have blunted Zika’s peak.
*”Even with prolonged maternal viremia, both pregnancies resulted in live births of apparently healthy babies.” Read more
Little is known about the exposure of infants to pesticides, despite their vulnerability and evidence of widespread dietary exposure among older children and adults. A study led by Emory Rollins School of Public Health researchers P. Barry Ryan, PhD, and Anne Riederer, ScD, seeks to improve methods for measuring pesticides in breast milk and infant formula.
â€œWe really donâ€™t know about how babies are exposed to pesticides in their everyday life,â€ says Riederer, assistant research professor, Department of Environmental and Occupational Health. â€œThere are very few published studies on this topic, and weâ€™d like to be one of the groups that actually publishes an analytical method that can be used by researchers in any country to be able to detect these different types of pesticides in breast milk.â€
Although the breast milk method will be pilot tested on samples collected from a birth cohort in Thailand, it will have broad applications for the U.S. population. Because these pesticides are widely distributed in the food supply, all U.S. infants are potentially exposed.
